Nested Annotation in JCodeModel

Question

I would like to create a CompoundIndexes annotation from the XML file like below.

However, I don't know how to put CompoundIndex Annotation with a parameter inside the CompoundIndexes Annotation. Here's what I've tried.

JAnnotationUse indexesAnnotation = currentClass.annotate(CompoundIndexes.class);

JAnnotationArrayMember arrayMember = indexesAnnotation.paramArray("value");

 JAnnotationUse indexesParameter = currentClass.annotate(CompoundIndex.class)
.param("def", some_parameter);

arrayMember.param(indexesParameter);

However, I end up getting the below result.

How can I only get the nested compoundIndexes part and get rid of the two componenet index annotations below?

In the otherword, how can a create an annotation and pass it into another annotation as parameter?

Looking at the source, it seems that param() is depreciated and suggests to use annotate() instead. Using annotate() sovles your problem:

JAnnotationUse indexesAnnotation = currentClass.annotate(CompoundIndexes.class);

JAnnotationArrayMember arrayMember = indexesAnnotation.paramArray("value");

arrayMember.annotate(CompoundIndex.class)
        .param("name", "email_age")
        .param("def", "{'email.id' : 1, 'age' : 1}");

Gives:

@CompoundIndexes({
    @CompoundIndex(name = "email_age", def = "{'email.id' : 1, 'age' : 1}")
})
